基于空轨接驳的铁水联运港口水平运输设备联合调度优化OA

Aiming at the"strong port and weak railway"issue caused by the inefficient railway-waterway intermodal connectivity in current port-railway systems,an automated container terminal system based on air-rail connection(ACTAR)was proposed.By introducing a monorail and two-way operation system of air-rail collection and distribution,the operation process and efficiency of multimodal container transshipment were studied.Combined with the characteristics of container horizontal transportation operation,the joint scheduling optimization of track guided freight vehicle(TGV)and automatic guided vehicle(AGV)was conducted.A multi-objective linear integer programming model was built to minimize the maximum completion time and total delay time of the transportation system.The non-dominated sorting genetic algorithm Ⅱ(NSGA-Ⅱ)was used to solve the simulation system.The results show that the proposed model and algorithm can realize the parallel and seamless collaborative operation between TGV and AGV.There is an optimal threshold for the configuration number of TGV and AGV.Exceeding the limit will lead to a lower or even worse improvement in the operation efficiency of the transportation system.The number matching of the two is a key factor affecting the integrated scheduling optimization results of horizontal transportation equipment.
